BUCKLE Application filed June 12, 1908.

f0 all whom it may concern:

Be it known that I, ARTHUR C. Storm, a citizen of the United States,residlng at Providence, in the county ofProvidence and State of RhodeIsland, have invented certain I new and useful Improvements in Buckles,of which the following is a specification.

My invention relates particularly to the cross-bars of buckles.

In buckles, particularly of large dimensions, the cross bars are liableto bend or become distorted under the strain of the sash, belt, or band;or to be broken away from the face plate to which they are soldered. Thedisproportionate quantity and thickness of stock required in such barsalso unduly increases the expense of their manufacture. The greatestsource of weakness at present is the hook portion upon which the strainparticularly centers. The rough square edges of the present bars alsocut, mutilate, and ruin the fabric of the sash or band.

The purpose of this invention is to correct the above enumeratedweaknesses and defects, and to attain the desired advantages 1 in asimple and inexpensive structure, to

g which ends essentially my invention conslsts Fig. 2, a section of thesame on line 00 m of Fig. 1. Fig. 3, a bottom plan of the blank afterits edges have been rolled. Fig. 4, a section of the same on line y y ofFig. 3. Fig. 5, a side elevation of the blank provided with undercutsand having one end bent. Fig. 6, a bottom plan of the same. Fig. 7, atop plan View of the complete bar mounted upon the buckle plate, andFig. 8, end elevation of the same.

Like reference characters indicate like parts throughout the views.

The cross bar is made by forming in the center of an oblong plate ofmetal, A, a longitudinally disposed flattened lip, B, V- shaped in'cross section. This lip is formed by successively punching with aV-shaped tool the center of the blank to form a longitudinal cup andforcing or compressing by swaging dies or otherwise the side wall, I)Z), of the cup into contact with each other leaving only the portion 5adjacent the base hol- Specification of Letters Patent.

low. Figs. 1 and 2 show the blank after the described treatment. Thelateral edges of the blank are trimmed, drawn, and bent or rolled underthe blank into marginal tubes or beads, C. Each of these tubes then havetheir lower faces sawed or undercut near both ends to form V-sha'pedcavities, 0, which permit the ends, 0, of the blank to be bentdownwardly and at right angles to the blank forming legs or supports. InFigs. 5 and 6, one of the legs is shown bent into final position. Thesupports or legs, 0, are bored before or after bending to form eyes, 0for re ceiving attaching threads for the belt strip. The tongue, B, isthen bent into hook form, and the legs, 0, have their ends fixed bysolder to the rear face of the usual buckle plate, D.

By this construction, it will be seen that the lateral tubes or ribs, C,impart a stiffness to the plate which prevents any bending thereof understrain, and present no abrasive surface to the fabric, and that a broadsoldering surface is likewise afforded at the ends of the legs.Furthermore, that the folded character of the hook, B, provides amaximum of strength and resistance at the point of the greatest strain.comparatively thin stock may be used in a crossbar constructed asdescribed.

hat I claim is,

1. A buckle cross-bar comprising a body portion, a hook upon the bodyportion, and integral tubular margins upon the body portion.

A buckle cross-bar comprising a body portion, a hook upon the bodyportion, legs upon the body portion, integral tubular margins upon thebody portion, and integral tubular margins upon the legs.

3. A buckle cross-bar comprising a body portion, a hook upon the bodyportion, integral marginal tubes upon the body provided with cavitiesnear their ends, integral legs upon the ends of the body, integral tubesupon the margins of the legs adapted to enter the cavities.

4:. A. buckle cross-bar comprising an oblong body portion and a hookintegral therewith and provided with folded walls compressed therefrom.

5. A. buckle cross-bar comprising a body portion and an integralflattened folded lip bent to form a hook.

6. A buckle cross-bar comprising a body portion having integraltherewith a recessed portion with flattened sides bent to form a hook.

7. A buckle cross-bar comprising a body portion, a hook integral withthe center of the body and compressed therefrom comprising a closed endand hollow base.

8. A buckle cross-bar comprising a body portion having integraltherewith a recessed portion with flattened sides bent to form a hook,and integral tubular margins upon the body portion.

9. 'A buckle crossbar comprising a body portion having integraltherewith a recessed portion with flattened sides bent to form a hook,integral tubular margins upon the body portion, and legs integral withthe body portion provided with tubular margins.

10. A buckle cross-bar comprising a body 1 portion having integraltherewith a recessed portion with flattened sides bent to form a hook,integral marginal tubes upon the body provided with undercut portionsnear their ends, and legs integral with the ends of the body providedwith inturned marginal portions adapted to enter the undercut portion 7of the tubes.

11. In abuckle, the combination with the buckle plate, of a cross-barcomprising a body having inbent lateral marginsprovided' 12. In abuckle, the combination with the.

buckle plate, of a cross-bar comprising a body having integral therewitha recessed portion with flattened sides bent to form a hook, integrallegs upon the body fixed to the buckle plate, and integral tubes uponthe margins of the body and of the legs.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
